Description

Technical Field

[0001] The utility model belongs to the technical field of bearings, and more specifically relates to a single-layer multi-lip outer spherical bearing sealing cover. Background Art

[0002] As a unique variant of the deep groove ball bearing, the design highlight of the outer spherical bearing is that the outer diameter of the outer ring adopts a spherical shape. This ingenious design allows the bearing to be precisely embedded in the concave spherical surface of the bearing seat, thereby achieving efficient self-aligning function and greatly improving the stability and flexibility of equipment operation. In actual applications, in order to ensure the excellent performance and long life of the outer spherical bearing, the internal installation of a sealing cover has become an indispensable link. The sealing cover plays the role of a guardian. It can not only effectively block the invasion of external dust, moisture and other potential contaminants, and protect the interior of the bearing from damage, but also shoulder the important task of preventing grease leakage to ensure the consistent lubrication state of the bearing. However, in actual use, the sealing performance of traditional sealing covers is often unsatisfactory, and leakage of lubricating fluid occurs from time to time, which not only increases maintenance costs but also affects the normal operation of the equipment. More prominently, during repair or maintenance, the separation process of the traditional sealing cover and the bearing requires the use of tools, which is more troublesome. Utility Model Content

[0022] like Figure 3 As shown, the disassembly auxiliary component 2 includes: a support ring column 201 and a sliding ball 202; the support ring column 201 is a circular ring structure as a whole, a groove is opened inside the support ring column 201, and the support ring column 201 is fixedly installed on the surface of the cover 101; the sliding ball 202 is slidably installed inside the slide groove of the support ring column 201.

[0023] like Figure 3 As shown, the disassembly auxiliary component 2 also includes: a spring 203 and a pull rope 204; the spring 203 is installed inside the groove of the support ring column 201 and is connected to the sliding ball 202; the pull rope 204 is slidably inserted into the groove of the support ring column 201 and is fixedly connected to the sliding ball 202. The pull rope 204 can facilitate the separation of the device from the bearing, and the spring 203 can play the role of elastically pulling the pull rope 204.

[0024] like Figure 4 As shown, the dust auxiliary cleaning component 3 includes: a support ring 301, a rotating groove 302 and a bottom ring 303; the support ring 301 is a circular ring structure, and the bottom of the support ring 301 is fixedly connected to the cover 101; the rotating groove 302 is opened at the top of the support ring 301; the bottom ring 303 is rotatably inserted inside the rotating groove 302.
